hallgren aa9280b287 Workaround for a problem with lock fields 
This problem showed up after delaing eta expansion until just before partial
evaluation

hallgren b93f817058 new-comp: delay eta expansion until just before partial evaluation 
This seems to work for the most part, but a problem showed up in WordsCat.gf in
the phrasebook.

hallgren bf5dfb2293 Nonlinear patterns in concrete syntax are now detected and reported as errors 
Before, they were silently converted to linear patterns.
Nonlinear patterns in MorphoCat.gf, ParadigmsGre.gf and ParadigmsFin.gf have
been make linear by renaming pattern variables.

hallgren 83283b0d6a Fix an old name shadowing bug in concrete syntax by removing the refresh pass 
The refresh pass does not correctly keep track of the scope of local variables
and can convert things like \x->(\x->x) x into \x1->(\x2->x2) x2. Fortunately,
it appears that the refresh pass is not needed anymore, so it has been removed.

hallgren d7916c1b08 Fix an old bug that prevented pattern matching agains values containg tables 
The function GF.Grammar.PatternMatch.isInConstantForm returned False for all
tables, causing matchPattern to fail, claiming that "variables occur in" the
term if it contains tables.

This problem is several years old, confirmed present in GF 3.2.10 (Oct 2010).

hallgren 08766585e6 gf -server: fix for directory URLs without a trailing slash 
When a browser requests a URL that refers to a directory, web server usually
redirect the browser to the same URL with a trailing '/' added, if one was not
already present. This is to prevent relative links in the returned document
from being interpreted relative to the parent directory instead of the current
document. This type of redirection was missing in gf -server.

hallgren fad63a14be Better error messages for attempts to redefine predefined constants 
Instead of just "syntax error", you now get e.g.

   PType is a predefined constant, it can not be redefined

This is a simple change in the parser.

hallgren 3b334b5707 minibar: more robust test for availability localStorage 
Minibar should now work if localStorage is disabled or unavailable.
(In Firefox, disabling cookies also disables localStorage.)
 2013-07-29 11:58:17 +00:00
hallgren e07a74df01 Allow cross origin requests to GF cloud & PGF services 
By adding a header

	Access-Control-Allow-Origin: *

to the HTTP responses, web browsers are informed that it is OK to call the
services from web pages hosted on other sites.

This is apparently supported in most modern browsers, so it should no longer
be necessary to resort to JSONP.

hallgren fe79e8cd25 gf-server.cabal: same changes as in gf.cabal for ghc-7.6 compatibility 2013-07-15 17:07:51 +00:00
hallgren bdfd663e91 Fix UTF-8 decoding problem in gf -server 
The package network-2.4.1.1 thoughlessly introduced a backward incompatible
change to the function Network.URI.unEscapeString, see

    https://github.com/haskell/network/commit/f2168b1f8978b4ad9c504e545755f0795ac869ce

This also affects the function Network.Shed.Httpd.queryToArguments, which is
used in GFServer.hs.

To remain compatible with older and newer versions of the network package,
we need to stay clear of queryToArguments and unEscapeString. A replacement
function has been added to server/URLEncoding.hs.
 2013-06-13 08:23:48 +00:00
hallgren d010dfdcfa Update the usage text for the --output-format option 
It needs to be updated manually when the list of available output format

hallgren c841c2c3c9 minibar: remove two more uses of with() 2013-04-25 15:08:26 +00:00
hallgren 7fe4ff8c46 minibar: fix bug that prevented minibar from working in Webkit browsers 
The with(...) {...} statement has different scoping rules in Webkit browsers
and Gecko browsers, so it is better to avoid it.
 2013-04-25 14:55:24 +00:00
hallgren 5fe680c837 PGF service: apply the token binding operator &+ to all linearizations 
The &+ operator is now consistently eliminated from the output of commmands
that produce linearizations. Before, only the commands translate and
translategroup did this.
 2013-04-24 18:32:53 +00:00

hallgren 6ae28fc693 GF home page: add "machine translation" in a meta keywords tag 
GF does not show up if you google for machine translation. This meta tag might
help, but in general I think it is better for SEO to mention relevant keyword
in the body text than to rely on meta tags.

hallgren c02d5b188b Prevent Unicode characters in warning messages from stopping grammar compilation 
When compiling a grammar containing characters that are not supported in the
current locale, warning messages could cause GF fail with 

  hPutChar: invalid argument (Invalid or incomplete multibyte or wide character)

With this quick fix, warning messages that can not be displayed are silently
truncated instead, and compilation continues.

hallgren d4fc60f260 PGF web API: generalize the 'to' parameter to accept a list of languages 
Some commands (linearize, linearizeAll, random, generate, translate and
translategroup) by default produce output in all languages supported by the
grammar and the 'to' parameter could be used to restrict output to a single
language. Now you can restrict the output to a list of languages. Languages
should be separated by spaces.

Also removed an unnecessary LANGUAGE pragma and reduced code verbosity.

hallgren 0feb386691 Faster regular expression pattern matching in the grammar compiler. 
The sequence operator (x+y) was implemented by splitting the string to be
matched at all positions and trying to match the parts against the two
subpatterns. To reduce the number of splits, we now estimate the minimum and
maximum length of the string that the subpatterns could match. For common
cases, where one of the subpatterns is a string of known length, like
in (x+"y") or (x + ("a"|"o"|"u"|"e")+"y"), only one split will be tried.

 2013-02-27 14:22:47 +00:00
hallgren 4f243fbf12 Fix for a PGF portability problem 
GF produced slightly different PGF files on 64-bit systems and 32-bit systems.
This could cause problems when a PGF was produced on a 32-bit system and used
on a 64-bit system.

To fix this, the GF compiler and the Haskell PGF run-time library now reads
and writes PGF files like the 32-bit version even when compiled on a 64-bit
system.

Note: the Haskell type Int is still used internally in GF, which could be
32 bits or 64 bits...
